longbook

A financial memory for your AI. longbook keeps your recurring money — subscriptions, insurance, EMIs, school fees, domains, renewals — as a meticulous, machine-readable memory that the AI you already use can read, fill, and build on. Your AI gathers from your statements and emails; longbook remembers, checks, and shows you every change for approval.

Native apps for iPhone and Mac (SwiftUI), one $38 purchase with a 7-day refund, one purchase unlocks every platform; longbook Cloud, $4 a month, covers what uses the server.

Your data is a folder of plain files you own — self-describing (llms.txt + a JSON Schema), synced through your own iCloud Drive.

Designed so it cannot hold secrets: no card numbers, no CVVs, no credentials — the schema and validators refuse them, which is what makes everything else safe.

Connects to your AI over MCP — locally for desktop AI apps, hosted for ChatGPT and phones.

Status

The domain engine (packages/core), the Swift data layer (packages/swift-core), the accounts and entitlements backend (supabase/) and the native app (apps/longbook) are all in place; the app runs on both platforms and ships through App Store Connect. Docs describe what exists today.

Layout

Path	What it is
`packages/core`	The domain engine — dates, money, selectors, insights, the data-policy scanner; pure TypeScript, no runtime deps
`packages/swift-core`	The same data layer in Swift, as a multiplatform package (iOS 17+, macOS 14+) shared by both app targets
`packages/swift-design`	The design system — colour, type, spacing, and the SwiftUI pieces both apps draw with
`packages/mcp`	The MCP server — the memory's read and write tools over stdio for the AI on the owner's machine, and the engine behind the hosted twin at `longbook.app/mcp`, which reads the pushed copy and takes writes as proposals
`packages/cards`	Self-contained HTML cards over the same numbers — the design system's tokens, exported once, feeding a second renderer
`supabase/`	Accounts, trial clock, entitlements, purchases, the hosted MCP and hosted copy, statement reading, report sharing
`apps/longbook`	The native SwiftUI app — one target building for iOS and macOS, with the Home Screen widget
`apps/longbook-site`	The static site at longbook.app — the pages, the guide and schema at stable addresses, and the edge functions behind `/mcp` and shared reports
